The Infratech WD-5224 MG is the 48-inch WD-series electric patio heater at 5200W/240V in 316 marine-grade stainless steel construction — the premium corrosion-resistance alloy for the harshest coastal and marine environments. 316 stainless offers significantly better corrosion resistance than the standard 304 stainless used in non-marine fixtures, designed for installations with continuous salt-spray exposure.
5200-watt configuration with WD-series bracket-mount installation. 240V residential single-phase electrical service. The WD-series differentiation from CD-series is the surface-mount vs flush-mount approach — WD fixtures hang from brackets rather than recess into ceiling surfaces.
Infratech manufactures in Gardena, California with components proudly made in the USA, backed by Infratech’s Three Year Warranty. UL/CUL listed indoor/outdoor. For oceanfront installations and any environment with continuous marine salt exposure, the 316 marine-grade upgrade is the operational requirement.
